Manufacturing Quality Control of Fmoc-Asp(OtBu)-OH
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe sample color and physical state (typically white to off-white crystalline powder), checking for foreign particles or caking. |
| Identification | Infrared Spectroscopy (IR) | Confirm structure by characteristic absorption peaks in the IR spectrum (e.g., C=O stretching vibration of the Fmoc group at ~1710 cm⁻¹, tert-butyl ester features). |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Measure in deuterated solvent (e.g., DMSO-d₆) and compare characteristic chemical shifts (e.g., aromatic protons of Fmoc, singlet for tert-butyl group). | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with UV detection (typically 210–220 nm); quantify main component using external standard or area normalization method. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Using the same conditions as assay, separate and quantify potential impurities (e.g., deprotected products, hydrolysis products, dimers). |
| Specific Optical Rotation | Polarimetry | Prepare a solution of defined concentration (e.g., 1% in DMF or methanol), measure optical rotation to verify L-configuration purity. |
| Water Content | Karl Fischer Titration | Determine water content using volumetric or coulometric method; control within specified limits (typically <1.0%). |
| Residual Solvents | Gas Chromatography (GC) | Headspace or direct injection to detect residual organic solvents from synthesis or purification (e.g., DCM, DMF, ethyl acetate). |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying Method | Measure weight loss after drying under specified temperature (e.g., 60–80°C) and time to assess total volatile content including moisture. |
| pH (if applicable) | pH Meter Method | Prepare a solution of defined concentration in water/organic mixture, measure pH to evaluate integrity of acidic groups (due to carboxylic acid, typically acidic). |
| Elemental Analysis (optional) | Elemental Analyzer | Determine percentages of C, H, and N elements; compare with theoretical values to confirm compositional consistency. |
